Abstract
The relationship between stock prices and the trade balance can be either negative or positive, depending on the signs of the wealth effect channel and the exchange rate channel. While previous studies examined this relationship in a time-invariant framework, we employ a time-varying approach so as to examine the dynamic correlations of trade balance and stock prices in the United States over the period 1792–2013. The results of our empirical analysis, which remain robust to alternative specifications, reveal that correlations between the trade balance and stock prices in the United States are indeed not constant, but evolve heterogeneously overtime. In particular, the correlations are, in general, significantly positive between 1800 and 1870, while significantly negative thereafter. The policy implications of these findings are then discussed.
Notes
In 2016, US exports were $2.2 trillion and imports were $2.7 trillion, with the trade deficit being about $500 billion.
The cost of production (land, labor, capital, taxes, incentives, etc.) in the exporting economy vis-à-vis those in the importing economy; The cost and availability of raw materials, intermediate goods and other inputs; Exchange rate movements; Multilateral, bilateral and unilateral taxes or restrictions on trade; Non-tariff barriers such as environmental, health or safety standards; The availability of adequate foreign exchange with which to pay for imports; and Prices of goods manufactured at home (influenced by the responsiveness of supply)
Ideally, we should be using real stock returns of the U.S. relative to its trading partners, since the trade balance of a country is intrinsically “relative”, i.e., it expresses a relative flow. However, due to lack of data on equity returns on the major trading partners of the U.S. over this prolonged period, restricts us to consider real stock returns of the U.S. only. In this regard, our approach is similar to that of Fratzscher and Straub (2009).
Some evidence that the trade balance reduces the real excess stock returns, and hence, the interest rate channel is at work can also be found now in Table 3, unlike what we observed for the real stock returns.
